Step 10: several self-traveling module transport vehicles slowly move, and by the first ring segment and the second ring segment close to reaching
It is required that spacing, completes preliminary group pair；
It is accurate to adjust the first ring segment and the second ring segment step 11: withdraw from self-traveling module transport vehicle respectively, when reaching
After group is to requiring, the first ring segment and the second ring segment, which are closed up, becomes total segmentation；
Step 12: by total fragmented transport at semisubmersible platform general assembly；
Step 13: total segmentation is lifted on semisubmersible platform；
Total segmentation is mounted on semisubmersible platform by the 14th step.
The top surface of the mobile moulding bed is crossed grid structure, and the lower section of mobile moulding bed is equipped with several supporting legs, between supporting leg there are
It is able to enter the space of self-traveling module transport vehicle.
Beneficial effects of the present invention: due to the adoption of the above technical scheme, each segmentation of semisubmersible platform is pre- by the present invention
It is first built on designed mobile moulding bed, after construction, then slideway general assembly is transported by self-traveling module transport vehicle
Domain carries out segment folding；Segmentation, ring segment group to being completed by self-traveling module transport vehicle, not only solving needs makes
The problem of carrying out integration of operation with more large caterpillars, substantially increases construction efficiency；Moreover, entire work progress is always
It is carried out in low level, after the completion of total segmentation, then transports semisubmersible platform general assembly place, complete semisubmersible platform general assembly work, greatly
The risk for reducing high-altitude construction greatly, improves the safety of construction.
